How do Blood Pressure Signals work on the Oura Ring 5?
Blood Pressure Signals track patterns in cardiovascular behavior during sleep when blood pressure is most stable and typically at its lowest. Oura does not provide direct blood pressure numbers but detects deviations from expected nighttime dipping patterns, which can signal potential cardiovascular risk. Users can also manually log blood pressure readings from external cuffs into the Oura app to enrich these insights.
What does Nighttime Breathing analysis provide?
Nighttime Breathing gives a 30-day rolling view of sleep-related breathing patterns and disturbances, expanding on earlier nightly breathing regularity metrics. The system identifies trends such as irregular breathing episodes, changes in respiratory rate, and correlations with sleep stages or readiness scores. This longer-term view helps users and clinicians spot potential issues like sleep-disordered breathing that might not appear in single-night data.
How does Health Radar integrate with other health data?
Members in the U.S. can import diagnosed conditions, medications, lab results, and allergies into the Oura app to create a fuller health picture compatible with Health Radar insights.
